So this chick pipped down low, took 30+ hours to hatch and needed help getting out. Its membrane was stuck to it and so I gently peeled it off and then left it to hatch the rest of the way. It is sticky looking and scrawny. It can not stand well. It uses its bad leg for balance. The joint where the leg bends is swollen and where the good leg has some tension/resistance when I move it, the bad leg is just limp. It can stand and hobble around. The other chicks are pretty abusive to it and so I have it separated but where they can still se each other. Any ideas or hints on what is wrong and if there is anything I can do for it.
